UNITED STATES NILS PETERSON, OF MOSCOW, IDAHO.

SEWER CLEANER,

Application filed March 15, 1920. Serial No. 365,876.

T all whom it may concern:

Be it known that I, NILS PETERSON, a citizen of the United States, residing at Moscow, in the county of Latah and State of Idaho, have invented a. new and useful Sewer Cleaner, of which the following is a specification.

This invention relates to improvements in devices for removing obstacles. from drain pipes, and more particularly to devices for flushing or cleaning basin or bathtub drain pipes.

The primary object of the invention is to provide a device of this character which will embody an attachment, with novel means for securing the same to a basin trap, or tub fitting.

A further object of the invention is to provide an attachment of this character, capable of being applied to traps of various sizes.

A still further object of the invention is to provide means for insuring a water tight connection between the attachment and the trap to which the same is applied, thereby directing the entire force of the water supply, to the drain pipe undergoing the cleaning operation.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawings Figure 1 illustrates a sectional view of a Cleaner attachment, constructed in accordance with the present invention, showing the same in operative relation with the trap used in connection therewith.

Figure 2 illustrates a modified form of clamping element.

Figure 3 illustrates an end view of a trap, illustrating the connection between the trap and cleaner.

Having reference to the drawing in detail, the reference character 5 designates the body, or main portion of the cleaning at tachment, and includes a relatively short pipe threaded throughout its length, exteriorly thereof, one end being turned as at 6 to provide an annular shoulder 7, adapted to cooperate with the outer edge 8, of the collar 9, which as shown is provided with arms 10 extending therefrom, each arm being provided with a right angled portion 12, for purposes to be hereinafter more fully described.

Tnis collar 9, is of a diameter to permit the collar to be readily moved into engagement with the shoulder 7, formed at one end of the body member 5.

The body member 5, is provided with internal threads, extending from the respective ends thereof, and terminating at a point a relatively short distance from the ends of said body member 5, said threads, being for the purpose of receiving the threaded portion of the supply pipe 14:, which has suitable connection with a source of water supply, not shown.

Positioned on the threaded portion of the body member 5, is a relatively thick washer 15, designed to closely fit within the walls of the trap, to which the device is applied.

Associated with the washer 15 is a disklike member 17 having a relatively large central opening 18, to permit the disklilre member 17 to be positioned on the body member 5, and moved throughout the length thereof, without engagement with the threads formed thereon.

As shown, the disk-like member 17, supports a large disk-like Washer 19, which is adapted to abut the washer 15, for forcing the same, and holding the same into position within the trap, while the disk-like washer 19, covers the upper surface of the trap, thereby preventing the escape of air or water, between the fixture and the trap to which the device is applied. I

In order that the disk-like washer 19, will be held into close engagement with the upper surface of the trap, to insure against leakage, I have provided an internally threaded collar 20, provided with winged portions 21 and 22, formed on opposite sides thereof, which winged portions provide efficient means to be grasped by the fingers of the operator, for rotating the collar and forcing the disk-like member 17 and disk washer 19, into engagement with the trap face.

In the event that it becomes necessary to use the device in connection with relatively small traps, it is only necessary to insert I the threaded" portion 23 of the substantially short pipe 24, within the threaded end of the body member, opposite to the end thereof which carries the annular shoulder 7, the opposite end of the pipe 24, being pro vided with integral extensions 25, terminating in right angled portions26, the operation of the extensions being the same as that of the extensions formed on the collar 9, 1O v in the form'previously described. 7

'In'this form, the nut27, supported on the pipe 24, is provided for insuring a 'fit between the trap and the pi'peJQ l, while the collar 28, whichisupports thedisk washinto close contact with the outer surface of the trap, to which the device is "applied, the collar 20 is rotated'in the opposite direction, with the result that the samevcon- ,tacts with the collar 2'8, whereby s'a id collar is moved correspondingly with the winged collar 20. i

The operation of the device as disclosed by'the drawings, is as follows: I

One end of the body member, is forced into the trap, having connection wit-hthe pipes to be flushed, the right angled portions of the arms 10 and 11, being moved to engage, under the usual guard toinied'integral with the trap casing, as shown by Figure 3, of the drawings.

through the pipes of the system, undergoing the cleaning operation.

-'Having thus described the'i'nvention, what is claimed is:" h, n j

In a device of the character described, a

g g body portion having aflahgeformed at its er 29, moves freely on the body ofthe device. I I

In order that the washer 29 may be held base, a collar on the body portion ancl 'engaging the flange, a pair of arms' extendin'g from the collar and having oppositely disposed liookniembers at'theirfreef ends, said hook members adaptedto "move under the guard "of a flush trap, a threadedm mber cooperating with the guard'for'securing'the collar to the body portion,'and'ineans on 'the body portioirand adapted tolbe moved 'towards' the guard for securing the body portion within the guard. v e I In testimony that I claimthe foregoing nature in the presence of twowitnesses.-
